Abstract

Hydrophilic addition polymers are made by copolymerizing 5 to 65% of styrene, vinylidene chloride or acrylonitrile, 25 to 90% of an alkyl ester of acrylic or methacrylic acid, e.g. a butyl ester, and 5 to 30% of acrylic acid, methacrylic acid, 4-vinyl-pyridine or N-vinylpyrrolidone. Polymerization is conducted in 1:2-dichloroethane, isopropanol, n-butanol, cyclohexanol or benzene or in water, using sodium laurylsulphonate as emulsifier, and catalysts used are azodiisobutyronitrile with or without later addition of benzoylperoxide; potassium peroxydisulphate with sodium metabisulphite; and hydrogen peroxide. In Examples, the following are polymerized:-styrene/n-butyl methacrylate /methacrylic acid, (A-H,K,L); styrene/ n-butyl methacrylate/4-vinylpyridine (I); styrene /n-butyl acrylate/acrylic acid (M, N, S); styrene/n-butyl acrylate/4-vinyl pyridine (O); styrene/n-butyl acrylate / N - vinylpyrrolidone (V); styrene / n-heptyl acrylate/acrylic acid (T); vinylidene chloride/n-butyl acrylate/acrylic acid (P, Q, R); and acrylonitril/n-octyl acrylate/acrylic acid (U).
